Got E85 today

[nos487]

I put my Turbo Tweak chip in today and put in straight E85. What a diffrence, turned boost up to 22 psi. and the driveability is the same as before with street chip. I now need to get wide band setup so I can tune. I ran car without touching chip and my 02's where around 670mv with .7 knock. I added 2% more fuel and 02's went to 780mv and 0 knock. Think I should do anything else or leave alone until I get WB. Paid $2.99 gallon

Cool, it is $2.999 here now, is holding, hope it starts going down again. Holding $1 cheaper than gas. Might start with it again.

Seems lean on a NB, 780mv, I would expect to be safer around 900mV. Looking at the slope of a NB O2, being higher in the mv is safer (rich is safe, lean can be dangerous....)

With E85 thats pretty lean......Ok for the street, but WB for the track or if
you going to pump it up.
Get the wide band...........

Unlike gasoline E-85 performs best when rich @ WOT. The majority of the cooling effect is realized during WOT with E-85. Its good stuff, especially when the boost comes on and all the while cleaning the engine :biggrin:

You'll notice the spark plugs will turn white and no more black crap out of the tailpipe... keep us informed

Narrow band is worthless for tuning at anywhere other than stoichiometric.

They are highly sensitive to temperature and pressure. Get the wideband.
